USB-PD-CHG-EVM-01: Output Power measurement with USB-C-PD-DUO-EVM

Jay Yoo

Hi Experts,

I was trying to measure TPS25750D's output current on USB-PD-CHG-EVM-01. And I decided to use USB-C-PD-DUO-EVM to draw current with electronic load.

But I noticed the maximum output from USB-C-PD-DUO-EVM is 5V/1.24A which was supposed to be 5V/3A.

I have configured TPS25750D with Source only mode. Do I need extra configuration on USB-C-PD-DUO-EVM as well? If not, Could you kindly guide me how to draw and measure 5V, 3A output from the USB-PD-CHG-EVM-01?

Please refer to my measurement setups as below.

Thanks,

Jay

Jay,

Please try regenerating the configuration binary. We corrected a few things in the GUI that may address this issue.
